I MPROVEMENT IN FIRE-PLACES.

Specification forming part of Letters Patent No. 122,410, dated January 2, 1872.

y SPECIFICATION. To all whom 'it may concern: Be it known that I, JOHN SMITH, of Pittsburg, in the countyof Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Fire-Placel and Grate; and I do hereby declare the following to bev a full,

' clear, and exact description thereof, reference being had to the accompanying drawing making a part of vthis specification, in which- Fi gurel is afront elevation of my improved fire-place and grate. Fig. 2 is a section through, the line mm, Fig. 1. Fig. 3 is a section through the line w w', Fig. 2. Fig. 4 is a rear perspecv `tive View of my improved grate-basket.

Like letters of reference indicate like parts in each.

My improvement relates to the Iconstruction i of lire-places and grates therefor; and consists in an improved construction, as hereinafter claimed, of the covering-tile, the grate, the tile surrounding it, and of the ash-pit below.

To enable others skilled in the art to make and use myinventi'on, Iwill proceedto describe 'nary form, and, standing vertically or nearly so, constitutes the back of the lire-chamber. The side tiles b also stand vertically, except at ltheir upper ends, where they gradually curve inwardly, so aste meet the endsof the arched covering-tile d.- The throat of the chimney for the escape of thesmoke is represented in Fig. 3 as closed by aslide, a', for the purpose of eX- cluding soot, ashes, Ste., in the Vsummer time when the grate is not in use. This arched cov-v ering-tile constitutes one feature of my invention. f Its value consists, in part, in its furnishing an improved deiiectin g and reiiecting surface, and presenting a much neater appearance than the ordinary flat tile. It is obvious that instead of being a circular arch the form may be polygonal, as illustrated by dotted lines in Fig. 3, without departing from a substantial.

videntity of construction.. The grate vitself is made with the usual front and bottom bars `c c. There is also cast with it a side and rear grating, c, along its two sides and rear end, the top of which is raised above the bottom bars any desired distance, say three or four inches, more or less, so as to leave apertures e for the admission of air to the lire. Y I consider it betiter to let them slope out a little, as shown, though thisis not necessary, provided the apertures c are not obstructed by the tile b. The side and back tiles b b are recessed or cut away along their inside lower faces, as at t', so that when the grate is in place the horizontal bars c of the side and rear gratings will iit neatly into such recesses, but still leave air-spaces around for the supply of air through the aperture e. These tiles terminate at or about the lower face of the grate or are cut away, as shown, and here the ash-pit spreads out under the tile, as at s s, so as to take in an ash-pan, f, the horizontal area' of which is larger than the area of the grate above. Hence it is obvious that the ashes from the grate will all be caught inthe pan, and th at none will drop over the side of the pan to be afterward shoveled up. The grate, it will be observed, is set well back, so that a summerfront can be put in to close up the nre-place without the necessary removal of the grate. The fender gis made with a close top, but open below, as at g', and v .the doors It `(having translucent panels h of mica, glass, or other suitable material) close I 'together with their lower edges resting on or near to the top of the fender g. The ash-pan 1 f has a ange, f', which comes back against the inner face of the doors h when the latter are closed.V Hence the air that supplies the y ordinary construction, and bituminous coal as a fuel, there is little or no heat evolved.

As the grate is not directlyv connectedwith the front, but is set in the tile, itcanvbe set rrrcnf out or in at pleasure, and thus it is adapted for. use in @muy phwff's Where the. Qrdliali grate, is objectionable.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A plain (as distinguished from a concave) faed vertical back tile, b', combined with the' side tiles b and arched covering-tile d, of the form and rela-tive arrangement substantially as set forth.

2. The tiles b b', recessed as at 1'., around and a little above that part of their faces which comes opposite to the rear and side gratings of the fre-basket, and in combination therewith, substznitizgtlly as described.

` 3- The tiles 1f b', recessed, as et S. 91.? weer.

eating at er about the lower. level ofA the gnat@- beskfft Se' t0, gli@ en eeh-nit both broeder and dee-per than'the grate-basket above, substantially asset forth.

4. The flange j" of the panf and the fender g, arranged relatively to the doors h so as to admit little or no air to the front of the re when the doors are closed While supplying it to the sides and rear, substantially as described.

In testimony whereof' I, the said JOHN SMITH, have hereunto'set my hand. Y
